The acronym âSAP,â for Systems, Applications, and Products in Data Processing, is the name of a corporation that specializes in business products and services designed to improve operational efficiency.
In 1932, Karl Jansky at Bell Labs revealed that stars and other objects in space radiated radio waves. Credit: NRAO/AUI. Radio waves have the longest wavelengths in the electromagnetic spectrum. They range from the length of a football to larger than our planet.Heinrich Hertz proved the existence of radio waves in the late 1880s. He used a spark gap attached to an induction coil and a separate spark gap on a receiving antenna.n 1932, Karl Jansky at Bell Labs revealed that stars and other objects in space radiated radio waves.

Transverse and compressional (longitudinal) waves are similar because have a frequency (and therefore a period), and a wavelength. that can be calculated. Waves come in either two major categories: electromagnetic or mechanical. Electromagnetic waves are light waves. They are energized particles that travel very quickly. They do not need a medium to travel, which means that they can travel through outer space where there is no matter. Mechanical waves are waves that require a medium (matter) to travel. These waves are considered to have two major shapes: transverse and compressional. For waves we can peform calculations using two equations: Frequency is the inverse of the time it takes for one cycle of the wave to occur.
